A few hours after grouting, as soon as the grout starts to dry (it become opaque), sweep the floor.
Within 48 hours from grouting and before the grout hardens definitively, wet the floor with an acid and buffered solution. Dilution depends on the type of surface (smooth or textured).
Spread the solution containing acid especially made for stoneware using a mop or a rotary brush for large surfaces, and featuring suitable discs, and let the solution work for a few minutes.
Rinse with warm water and clean cloths and repeat several times until all stains and residues have been eliminated. Make sure to change rinsing water several times.
Complete by drying. Pay attention to prevent contact of the acid solution with other materials (metal, marble, etc.).
ATTENTION!! Epoxy-based grout cannot be cleaned when it has completely hardened other than mechanically with risks to the surface of the tiles. For more information and recommendations, consult the grout manufacturer. Care must be taken on inlayed, polished and anti-slip products; for the latter in particular, the use of a floor-washing machine combined with the action of an acid detergent helps reach the spaces between adjacent tiles and clean them properly. If such a cleaning procedure is not carried out, or if such cleaning is carried out too late, the grout residue creates an extremely absorbent film, which holds dirt, making the surface difficult to clean: in this case, Ceramiche CAESAR S.p.A. will not be liable for any damage caused to the sur
CLEANING AND CARE
If the cleaning rules after installation are followed, routine maintenance, i.e. everyday cleaning to remove dirt from traffic and general use of the tiled surface, is reasonably easy.
We would like to remind you that porcelain stoneware is a product with excellent technical features which allow for the highest grade of mechanical wear and resistance to acids (except for hydrofluoric acid and its derivatives) and alkalis, features which are added to a high aesthetic quality.
Porcelain stoneware has a low absorption level, another intrinsic characteristic of the product. As detailed in the technical sheets, absorption levels are very low in the production process CAESAR adopts, and all our products will achieve the best results for any kind of specific application.
Ordinary maintenance must be carried out using specialist detergents to remove stains but these detergents must not leave a wax, film or membrane residue. Rinsing well with plenty of clean water is a fundamental part of the cleaning procedure, therefore we advise against the use of products which state that they “do not need rinsing”. Bright colored products, in particular white and extra-white tiles, especially those with a polished, honed and “lucidato” finish, are very delicate and, although for all intent and purpose are hygienically clean, they tend to stain more easily than darker tiles.
It is therefore necessary to remember that these particular products require careful maintenance. White products meet the UNI EN ISO 14411 Annex G 10545-14 standard (calculation of stain resistance), for top quality materials in terms of cleanability: certain types of dirt need an extra-ordinary maintenance procedure using specific detergents according to the type of stain. We would like toinform you that, the above mentioned standards do not cover rubber stains (shoes, heels, mats, etc...) especially where these kinds of stains are frequent: therefore, Ceramiche CAESAR S.p.A. will not be held liable for any such damage to the surface of these products. All types of surface of the Caesar range can be washed with clean water or water and up to 50% of bleach or alcohol. We recommend periodical cleaning with basic products or a micro-foaming basic product for porcelain stoneware, followed by thorough rinsing and drying.
Any stains or marks can be removed quite easily since porcelain stoneware has very low absorption properties and resists acids and bases.Depending on the type of stain, you can use:
- ACIDS for INORGANIC stains,
- BASES for ORGANIC stains,
- SOLVENTS for SYNTHETIC stains.
The use of common aggressive acids (such as muriatic acid for instance) must be avoided. These products remove residues of grout but also irreparably damage the grout within the joint. Also pay attention to all products containing HYDROFLUORIC ACID (HF) SINCE THEY IRREPARABLY DAMAGE ALL CERAMIC SURFACES. For information about products appropriate for the type of stain, which can be easily found on the market, refer to the following table.
The above suggestions are a result of research, laboratory tests and several years’ experience. However, the cleaning features of the materials may vary significantly according to the different installation methods, conditions of use, types of surface and destination. As ageneral rule, the higher the anti-slip values of the tiles are, the greater cleaning inconveniences may arise. The professional operator in charge of maintenance and cleaning shall always check the surface condition before proceeding with any cleaning and/or maintenance operation (we would suggest to test some tiles before installation). Caesar declines any liability with reference to cleaning and maintenance operations in case of heavy conditions of use (such as mechanical workshop or spaces presenting oily residues or tyre marks), bad installation work or wrong cleaning operations, it is agreed that Caesar shall not be liable for any event, damage or defect due to wrong installation of the tiles, faulty cleaning and maintenance operations or inadequate choice of the type of material to be laid or of the adhesives used in a certain destination of use
